Summary:To provide a soft magnetic material composition, a core, and a coil-type electronic component that can achieve a high initial magnetic permeability.SOLUTION: A soft magnetic material composition includes a plurality of soft magnetic alloy particles 21 and 22. The soft magnetic alloy particles contain an element M and iron. The element M has a stronger ionization tendency than silicon. Regions 30 and 31 between the soft magnetic alloy particles have an amorphous layer of a Si-M oxide or a Si-M composite oxide.SELECTED DRAWING: Figure 3 【課題】高い初期透磁率を達成できる軟磁性体組成物、コアおよびコイル型電子部品を提供する。【解決手段】軟磁性体組成物は、複数の軟磁性合金粒子２１、２２を有する。軟磁性合金粒子は、元素Ｍと鉄を含む。元素Ｍは、ケイ素よりイオン化傾向が強い。軟磁性合金粒子の間の領域３０、３１には、アモルファス層であるＳｉ−Ｍ酸化物またはＳｉ−Ｍ複合酸化物を有する。【選択図】図３
